ERROR 2024-05-03T15:39:54.942Z f24c58f2-6eda-4d95-b070-50d7c32d4b03 Error fetching pages: { message: 'URL not included in the external fetch backend permissions: https://f4e3-41-250-195-224.ngrok-free.app/api/page. Visit go.atlassian.com/forge-egress for more information.', name: 'REQUEST_EGRESS_ALLOWLIST_ERR', status: 403 }
eventhough i already modified the manifest

modules:
  jiraServiceManagement:portalFooter:
    - key: jsm-chatbot-hello-world-panel
      resource: main
      resolver:
        function: resolver
      viewportSize: medium
  function:
    - key: resolver
      handler: index.handler
resources:
  - key: main
    path: static/hello-world/build
app:
  id: ari:cloud:ecosystem::app/880a5aaf-ccb0-4b00-86ba-d70ee500ed7a
  
permissions:
  scopes:
    - read:servicedesk-request
    - read:page:confluence
    - read:confluence-space.summary
    - read:confluence-content.all
    - read:confluence-content.summary
  external:
   fetch:
    backend:
      - 'https://f4e3-41-250-195-224.ngrok-free.app/api/page'  ,

and this is my code

resolver.define('getPages', async () => {
  try {
    const res = await api.asApp().requestConfluence(
      route`/wiki/rest/api/content?type=page&expand=body.view`,
      {
        headers: {
          'Accept': 'application/json',
        },
      }
    );
    const data=await res.json();

    const formattedPages = data.results.map(page => ({
      id: page.id,
      title: page.title,
      content: page.body && page.body.view && page.body.view.value && page.title !== "Support" && page.title !== "Template - How-to guide" && page.title !== "Template - Troubleshooting article" && page.title !== "Getting started in Confluence" && page.title !== "Overview" ? formatHtmlToText(page.body.view.value) : ''
    }));

    const endpointUrl = 'https://f4e3-41-250-195-224.ngrok-free.app/api/page';
    const response = await api.fetch(endpointUrl, {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(formattedPages),
    });
    if (response.ok) {
      console.log('Pages sent successfully to external endpoint for registration');
    } else {
      console.error('Failed to send pages to external endpoint:', response.statusText);
    }


    return formattedPages;
  } catch (error) {
    console.error('Error fetching pages:', error);
    throw error;
  }
});

// Function to format HTML content to plain text
const formatHtmlToText = (htmlContent) => {

  return htmlToText(htmlContent) || "";
};

thank you in advance

Hi, I don’t have an environment to test right now but just to rule out some possibly manifest issues, have you tried running $ forge lint to check the manifest, and then $ forge deploy plus reinstall ($ forge install)?
